It's been said many times that the best setup for the HR is the stock with KN dro ins. That is what I have. However I would like to get some polished intake tubes to replace the ugly rubber ones. Does anybody make these for the HR? I could not find anything online.

 

cobb makes a smooth silicone version so theres no ribs

 

OP, I can't answer your question. But as a side note (and in fact) the Stillen Gen 3 and Injen intakes will both give you higher HP than K&N drop-ins.

 

I was looking for aluminum polished. However, I aluminum conducts heat a lot more than rubber, so it would warm up as the engine bay gets hot and eventually affect the intake air temps. What do you think?
